To find x intercept ,
let f(x) = y
therefore y= 8x - 4
in solving for x intercept, me plug in y = 0
thus
8x - 4 =0
solving for x
8x = 4
dividing through by 8
8x/8 =4/8
x =4/8
x =1/2
therefore, the x intercept is 1/2
I have a lot to say about the
-212 feet, -122 feet, 2 feet, 202 feet
Using the circle theorems, we have proven that m ∠RTW = 15°
<h3>Circle theorems </h3>
From the question, we are to prove that m ∠RTW = 15°
In the given diagram,
measure of arc ST = 30°
∴ m ∠SRT = 30°
m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)
Also,
∠T = ∠W (<em>Radii of the same circle</em>)
∴ m ∠SRT = ∠T + ∠T
m ∠SRT = 2 × ∠T
30° = 2 × ∠T
∠T = 30° /2
∠T = 15°
∴ m ∠RTW = 15°
Hence, we have proven that m ∠RTW = 15°
